Reviews
I have used at least
"I have used at least 3 different treatmrnts this year and Envy was the third one. I still remove some string algae manually, but it is a much, much better water condition now! I think unusual situation with rain and temperatures this yearcreally affected our pond and the gardrn!"

I have used pond clear
"I have used pond clear extra which killed my blanket weed also two I ltr bottles of pond clear over an 8 week period and still my pond is green. i have also checked the balance of my pond which seems ok."
— David L. (5/5)
Did the job
"My pond had become very green during the recent hot weather. My usual treatments didn’t seem to be working. After reading the positive reviews I decided to try Envii Klear Xtra. It’s taken 7 weekly treatments but the water is now clear (the label does say that it can take 6 - 8 weeks to clear very green or murky water). I also cleaned the pond filter twice a week, as recommended. It was amazing how much sludge was accumulating in just 3-4 days). You need to be patient as positive results do take time, but I’d highly recommend this product."
